Who called from 5405950671

Calls but won't leave a message. CallerID says "UNASSIGNED".

Received call this evening with this number. Caller ID read "unassigned", so I didn't answer. No message left.

Received call multiple times this time they asked for me by my legal name. and I said "This is him" and they hung up

This is a sponsorship drive raising funds for Veterans to get jobs. They didn't indicate quite how the money would help Veterans, and they hung up on me without any greeting when I told them I'm strapped.

They call me by my first name.  I hung up.  Really!
